Clumps as multiscale structures in cosmic noon galaxies

Star-forming clumps have been found to significantly influence the star formation of gas-rich z > 1 galaxies. Using public data from JWST/NIRCam (Cosmic Evolution Survey; COSMOS-Web) and Atacama Large (sub-)Millimeter Array (ALMA; Fiber-Multi Object Spectr ...

Low Surface Brightness structures from annotated deep CFHT images: effects of the host galaxy’s properties and environment

Oliver Müller

Hierarchical galactic evolution models predict that mergers drive galaxy growth, producing low surface brightness (LSB) tidal features that trace galaxies’ late assembly. These faint structures encode information about past mergers and are sensitive to the ...

The Pristine Inner Galaxy Survey (PIGS): XI. Revealing the chemical evolution of the interacting Sagittarius dwarf galaxy

Pascale Jablonka

Context. The Sagittarius dwarf spheroidal galaxy (Sgr dSph) is a satellite orbiting the Milky Way that has experienced multiple stripping events due to tidal interactions with our Galaxy. Its accretion history has led to a distinct stellar overdensity, whi ...

A 3D view of dwarf galaxies with Gaia and VLT/FLAMES: II. the Sextans dwarf spheroidal

Salvatore Taibi

The Sextans dwarf spheroidal galaxy has been challenging to study in a comprehensive way as it is highly extended on the sky, with an uncertain but large tidal radius of between 80- 160 arcminutes (or 3- 4 kpc), and an extremely low central surface brightn ...

An Indication of Gas Inflow in Clumpy Star-forming Galaxies near z ∼ 1: Lower Gas-phase Metallicities in Clumpy Galaxies Compared to Nonclumpy Galaxies

Pascale Jablonka

Despite the ubiquity of clumpy star-forming galaxies at high-redshift, the origin of clumps are still largely unconstrained due to the limited observations that can validate the mechanisms for clump formation. We postulate that if clumps form due to the ac ...

TangoSIDM Project: is the stellar mass Tully-Fisher relation consistent with SIDM?

Yannick Michael Bahé

Self-interacting dark matter (SIDM) has the potential to significantly influence galaxy formation in comparison to the cold, collisionless dark matter paradigm (CDM), resulting in observable effects. This study aims to elucidate this influence and to demon ...

Exploiting the diversity of modeling methods to probe systematic biases in strong lensing analyses

Aymeric Alexandre Galan

Challenges inherent to high-resolution and high signal-to-noise data as well as model degeneracies can cause systematic biases in analyses of strong lens systems. In the past decade, the number of lens modeling methods has significantly increased, from pur ...

Euclid preparation LI. Forecasting the recovery of galaxy physical properties and their relations with template-fitting and machine-learning methods

Frédéric Courbin, Georges Meylan

Euclid will collect an enormous amount of data during the mission’s lifetime, observing billions of galaxies in the extragalactic sky. Along with traditional template-fitting methods, numerous machine learning (ML) algorithms have been presented for comput ...

A magnetar giant flare in the nearby starburst galaxy M82

Volodymyr Savchenko

Magnetar giant flares are rare explosive events releasing up to 1047 erg in gamma rays in less than 1 second from young neutron stars with magnetic fields up to 1015-16 G (refs. 1,2). Only three such flares have been seen from magnetars in our Galaxy3,4 an ...

Energy dependence of the knee in the cosmic-ray spectrum across the Milky Way

Andrii Neronov

The all-particle spectrum of cosmic rays measured at Earth has a kneelike feature around 4 PeV. A priori, it is not clear if this is a local feature specific to the Solar neighborhood in the Milky Way or if it is a generic property of the Galactic cosmic-r ...

Prospects for detecting the circum- and intergalactic medium in X-ray absorption using the extended intracluster medium as a backlight

Yannick Michael Bahé

The warm-hot plasma in cosmic web filaments is thought to comprise a large fraction of the gas in the local Universe. So far, the search for this gas has focused on mapping its emission, or detecting its absorption signatures against bright, point-like sou ...

Dark Energy Survey Year 3 results: Cosmological constraints from galaxy clustering and weak lensing

Jonathan Andrew Blazek

We present the first cosmology results from large-scale structure using the full 5000 deg(2) of imaging data from the Dark Energy Survey (DES) Data Release 1. We perform an analysis of large-scale structure combining three two-point correlation functions ( ...
